(3x-10)-(15-2x)=5
比如:5(2+3)=5*2+5*3=10+15=25那么:(x+3)^3=.(x-3)^4=.(x*3)^5=.(x/3
若(x-2)/5-(x+3)/10>(2x-5)/3-3,求|2x-15|-|16-2x|的值
方程咋解:3(3X-2)=10-0.5(X+3.5) X+5Y=21 9x+2y=15 x-y=3 3x+4y=10 3
解方程:x-5/8x=15 2/5x-3/10x=120
〔2x10^-3}x〔5x10^13〕和〔3x10^-5〕^2\〔3x10^-1〕^2
x-5/15
先观察下列格式,(x+3)(x+5)=x^2+8x+15(x-3)(x-5)=x^2-8x+15(x+3)(x-5)=x
先观察下列格式,(x+3)(x+5)=x^2+8x+15(x-3)(x-5)=x^2-8x+15(x+3)(x-5)=x
5X-2(X-3)=15 X-3(2X+1)=6X-4(5-3X)
